This paper shows the application of Savitzky-Golay (SG) filter for image processing. Various filters are used to extract required information from an image. SG filter works based on local least square polynomial regression method which preserves the width and height of the information signal and reduces the noise amount which improves the filter performance compared to other filters. The image details are preserved more in SG filter compared to other filter.
